Definitions

the subject of present invention is aqueous solution for wood preservation against wood pests, and to improve resistance of wood against biotic and abiotic factors of decay.
Wood is exposed to various biotic and abiotic factors of decay. These processes are necessary and required in the nature, but when wood is used for construction purposes, we would like to slow them down as much as possible. This is can be achieved by using chemical wood preservatives.
Copper effectiveness against wood decay fungi makes it important constituent of wood preservatives for almost 200 years.
the use of copper compounds for biocidal purposes has increased. The reasons are: copper compounds are relatively safe, development of pathogens has been minimal; pathogens show increased tolerance against organic fungicides after extended period of use, and thirdly increase in government regulations and restrictions (or outright banning) of alternative products due to their toxicological or environmental impacts.
traditional copper based wood preservatives had an important drawback; copper did not get fixed into wood and was prone to leaching out of wood.
arsenic salts are banned for almost 15 years.
boron salts were introduced instead.
arsenic was replaced by fluorine compounds.
ethanolamine is a component of several copper based wood preservatives that are available on the market. This includes copper-quat, copper dimethyl-dithio-carbamate, and copper azole. In those preservatives, boron, quaternary ammonium compound or azoles are used as cobiocides, and ethanolamine as fixative. However, detailed molar ratios between copper and amine are not known.
Solution for wood preservation offers environmentally acceptable protection of wood against most important wood decay fungi, including white rot, brown rot species as well as copper tolerant isolates. Additionally, wood treated with these preservatives has increased resistance against insects (house longhorn Beatle) and termites. On the other this preservative solution does not contain chromium and arsenic.
Copper ensures effectives against most important wood decay fungi, ethanolamine and carboxylic acid ensures proper fixation and quaternary ammonium compound and boron offers protection against insects, termites and copper tolerant fungi.
composition of solution for wood preservation according to the present invention is optimized using two criteria, after extensive laboratory testing. Those two goals are: to decrease copper leaching and to increase effectiveness against wood destroying organisms (wood decay fungi, insects, and termites).
Wood preservative solution described in this invention is aqueous solution consisting of:
molar ratio between copper and ethanolamine in preservative solution is important as well. This ratio influences on the price of preservative solution and its resistance against copper leaching. In the most of preservatives the solution molar ratios Cu:amine are lower than 1:12.
One of the exemptions is Kuproflorin produced by Regeneracija, Slovenia.
Acceptable copper-amine molar ratios are between 8:1 and 3:1. The best ratio is influenced by copper source used, co-biocides, and other additives. Generally speaking, more additives requires higher copper amine molar ratio. The lowest copper leaching is determined at specimens impregnated with aqueous solution consisting of copper, boron, ethanolamine, quat where molar ratio between copper and amine was between 1:5 to 1:6. In solutions where molar ratio was lower than 1:4, copper precipitated.
composition of preservative solution described in this patent is aqueous solution consisting of ethanolamine, copper (II) sulphate, disodium octaborate tetrahydrate, alkylbenzyldimethyl ammonium chloride, and octanoic acid in the following composition:
Wood impregnated with the solution for wood preservative according to the present invention is resistant against termites ( Kalotermes flavicolis ) as well.
